Abstract excerpt
Allelic variants of kappa-casein and beta-lactoglobulin were used to estimate chromosome substitution effects on transmitting abilities for yield traits among sons of two Holstein sires. Sire 1 was a heterozygote for both loci, whereas sire 2 was a heterozygote for beta-lactoglobulin only. Transmitting abilities for fat percentage and the exchange of protein and fat (protein yield minus fat yield) were influenced...
